Application June 20, 1939, Serial No. 280,085

' 3 Claims. (cl. res-9) Fifth, to provide an air cleaner of this class in which the air filter is rotated by relati iie movement of the air with the motor;

Sixth, to provide an air cleaner of this class which is applicable for use in connection with any motor;

Seventh, to provide an air cleaner of this class which is readily and easily attached to the motor for use;

Eighth, to provide an air cleaner of this class in which the filter rotating speed is variedv substantially with the speed of the vehicle upon which the cleaner is mounted; and

Ninth, to provide an air cleaner of this class lar parts and portions throughout the several .views of the drawings.

The outer casing I, inner casing 2, intermediate casing 3, partition 4, casing members 5 and 6, gear casing 1, gear shaft casing and support 8, shafts 9, l0, II and I2, worm pinions l3 and I4, worm gears l5 and I6 and spur gears I1 and I8, gear supporting discs l9 and 20, bar 2i and the sealing clamp member 22 constitute the principal parts of my air cleaner.

The outer casing l is of substantially hollow cylindrical shape and is provided in its upper side above the center with elongated holes la,

tion, eflicient in its action and-which will not .readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is an elevational view of my air cleaner showing portions broken away and in section to facilitate the illustration; Fig. 2' is a fragmentary sectional view taken from the line 2-2 of Fig. 1; Fig. 3 is an enlarged fragmentary sectiona1 view taken from the line 3-3 of Fig. 1; Fig. 4

is an enlarged fragmentary sectional view taken from the line 4-4 of Fig. 1; Fig! 5. is a fragmentary sectional view taken from the line 5-5 of Fig. 1; Fig. 6 is a fragmentary sectional view taken: from the line 6-6 of Fig. 5 and Fig. 'I is a fragmentary sectional view taken from the line 1-1 of Fig. 5.

Similar characters of reference refer to simicasing 'l are secured together by means of the bolts In. To the flange portion lg is clamped and sealed the annular inner casing support 2a by means of the annular V shaped sealing clamp member 22 and its respective bolt 22a. The normally lower side of the outer casing l is imperiorate and serves as an oil reservoir, as shown best in Fig. 5. v

, The inner casing 2 is of substantially hollow cylindrica1 shape, enclosedat one end and covered at its open end with a screen portion 2b which is soldered or otherwise secured thereto.

' The inner casing is secured to its support 2a by means of an annular flange 20 by the bolts 2d, as shown best in Fig. 7. It will be noted that the inner casing 2 is mounted centrally in the outer casing l and is provided with holes 2e in its upper side. Securedin and communicating with both sides of said inner casing support 2a is a hollow upwardly extendingtube 2) in the upper end of which is screw threaded a plug 2g as shown best in Figs. 1 and 3 'of the drawings. It will be noted that said tube 2f extends upwardly to substantially the oil level in the outer casing l, as shown in Fig. 5 of the drawings.

Positioned between the intermediate casing} and the partition 4 is an annular massof metal filter wire 30. as shown best i rFigs. 5 and '7. It will be noted that the internejdiate casing 3 and the partitions 4 are annular .ntl foraminous and are clamped between the ca sing? members 5 and 6 by means of the rods 5a and nuts 5b which are screw threaded on the ends of the rods 5a. Se

cured on the end of each rod 5a adjacent the casing member 6 is a plate-spring 50 which engages the inner casing support 2a and holds said casing member in place. It will be noted that the casing members 5 and 6 are of substantially fiat circular shape and that the casing member 6 is provided with a central hole 6a through which the inner casing 2 extends. Secured in and extending from the center of the casing member 5 Y is a pin 5d. Also spaced therefrom are lugs 5e as shown best in Figs. 1 and 7 of the drawings. This pin Ed is fitted in a hole 2Ia of the bar 2|, and engaging the side of eachend of the bar 2| is one of the lugs 5e as shown best in Figs. 1, 4 and 7 of the drawings.

The gear casing l is substantially hollow cylindrical in shape and is provided with a flanged portion la in which are fitted the bolts lh. Secured to said gear casing 1 by means of the bolts lb is the gear shaft casing and support 8, which is of substantially hollow frusto conical shape and is fitted at its smaller end with a fiber bearing 8a in which the gearshaft 9 is journalled. On one end of the gear shaft 9 is a wind wheel 9a which is provided with concavo-convex blade portions 9b. The gear shaft 9 is journalled at its one end in a fiber bearing 90 which is secured spectively and are for the purpose of reducingv the end playof the gear shaft 9.

The gear shaft 10 is journalled in the brackets Illa and I01) and mounted on the gear shaft l0 adjacent the bracket lob is the worm pinion H which meshes with the worm gear l6. Mounted on the gear shaft [0 intermediate said worm pinion l4 and the bracket Illa is the worm gear l5 which meshes with the worm pinion I3.

The gear shaft II is journalled in the gear supporting. discs I9 and and mounted on said gear'shaft ll are the worm gears l6 and spur gear II. The spur gear l'l meshes with the spur gear-l8 which is mounted on the gear shaft l2.

The gear shaft I2 is journalled in a journal member l2a which is secured to the gear supporting disc 20 and said shaft l2 extends through said supporting disc 20. On the one end ofthe gear. shait I2 is the bar 2| as shown best in Figs. 1-

and 7 of the drawings.

The operation of my air cleaner is substantially as follows:

Assuming that the air cleaner is attached to the carburetor of an automobile motor, and that the automobile is in motion, the current of air acting on the concavo-convex blade portions 9b of the air wheel 9a turns the gear shaft 9. The bar 2| is turned by means of the gear shafts}. III, II and I2, the worm pinlons l3 and I4 and the worm gears li and I6 and spur gears l1 and It. The casing members 5 and the intermediate casing 3, partition 4, wire filter mass, la

and the rods 5a are all revolved inside the outer casing l and through the oil A by means of the lug portions ie in engagement with the bar 2|. It will be noted that one complete revolution of Intermediate said fiber bearings 8a the bar 2| occurs approximately once every hour, while the air cleaner is in operation.

The air entering the inner casing 2 through the screen 2b passes upwardly through the holes 2e, the partition 4, wire filter mass 3a, intermediate casing 3 and the holes la of the outer casing I and downwardly inside the casing portions lb, lo and Id and into the carburetor through the connection is, all as shown by arrows in Figs. 5 and 7 of the drawings. It will be here noted that the Wire filter mass 3a-being constantly rotated through the oil A readily collects dirt, sand and other undesirable matter from the air as it passes through said filter mass 3a.

If it is desired to clean the air cleaner, the bolt 22a of the sealing clamp member 22 is loosened and said sealing clamp member 22 is removed permitting the inner casing 2 and its respective support to bev removed and also permitting the removal of the filter mass 3a, and its respective casing members. new oil to the oil filter, the plug 29 is removed and oil is supplied through the tube 2).

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an air cleaner of the class described, the combination of an outer casing provided with perforated portions in its upper side, an inner casing open at one end and provided with perforated portions in its upper side and positioned in said outer casing, a revolubly mounted filter -mass positioned intermediate said casings and a casing portion surrounding said outer casing enclosing said perforated portions thereof, said casing portion surrounding'said outer casing provided with a downdraft carburetor connection air conductor portion at its lower side.

2. In an air cleaner of the class described, the

combination of an inner air inlet casing, a revolubly mounted filter mass surrounding said inner casing, an outer casing enclosing said revolubly mounted filter mass and a casing portion' surrounding said outer casing provided with an air conductor connection portion at its lower side, said inner casing and outer casing each provided with perforations in their upper side communicating with the interior of said casing portion surrounding said outer casing.

voir in said outer casing around the lower portion of said revolubly mounted filter mass.
